Can't join MCPE Server

Hello,

I have a problem with my MCPE Pocketmine 3.13.0 / MCPE 1.16.1 Server. When it's online, I can join the server, all is going well, but when I join, I see the world for less than a second, then I get kicked and this dirt background appears and says Internal server error. When I look in the Log, it says Blocked {my ip} for 5 seconds. Please help me. I'd like to play on my server again very soon.

oh, I typed the wrong number, I meant 3.14.0

why do no other people answer?

That's my log. The error begins at line 197.
